Huntingtin grabs a hammer: DNA repair in HD

... Mutant huntingtin comes to work and botches the job In HD mice, lowering ATM levels was beneficial, perhaps because it dulled ATM’s misdirected DNA repairs and zealous demolitions. But if huntingtin itself helps fix DNA lesions, perhaps there’s a difference in how normal versus mutant huntingtin mov ...

Polycomb Group Proteins and Cancer

The Polycomb-group proteins (PcGs) are a family of proteins that use epigenetic mechanisms to maintain or repress expression of their target genes. They were originally discovered in Drosophila (fruit flies), though they've been shown to be conserved in many species due to their vital roles in embryonic development. These proteins' ability to alter gene expression has made them targets of investigation for research groups seeking to understand disease pathology and oncology.
